   2  * VARIANT test program
   3  *
   4  * Copyright 1998 Jean-Claude Cote
   5  *
   6  * The purpose of this program is validate the implementation
   7  * of the APIs related to VARIANTs. The validation is done
   8  * by comparing the results given by the Windows implementation
   9  * versus the Wine implementation.
  10  *
  11  * This program tests the creation/coercion/destruction of VARIANTs.
  12  *
  13  * The program does not currently test any API that takes
  14  * arguments of type: IDispatch, IUnknown, DECIMAL, CURRENCY.
  15  *
  16  * Since the purpose of this program is to compare the results
  17  * from Windows and Wine it is written so that with a simple
  18  * define it can be compiled either in Windows or Linux.
  19  *
  20  *
  21  * NOTES
  22  *       - The Variant structure in Windows has a non-named union. This means
  23  *       the member of the union are accessible simply by doing pVariant->pfltVal.
  24  *       With gcc it is not possible to have non-named union so it has been named
  25  *       'u'.  So it's members are accessible using this name like so
  26  *       pVariant->u.pfltVal.  So if this program is compiled in Windows
  27  *       the references to 'u' will need to be take out of this file.
  28  *
  29  *       - Also the printf is a little different so the format specifiers may
  30  *       need to be tweaked if this file is compile in Windows.
  31  *       Printf is also different in that it continues printing numbers
  32  *       even after there is no more significative digits left to print.  These
  33  *       number are garbage and in windows they are set to zero but not
  34  *       on Linux.
  35  *
  36  *       - The VarDateFromStr is not implemented yet.
  37  *
  38  *       - The date and floating point format may not be the exact same format has the one in
  39  *       windows depending on what the Internatinal setting are in windows.
